MACHINE FOR WINDING PIPES 0R PIPE-COVERINGS.

Specification of Letters Patent.

Patented May a, 1915.

Application filed .T une 14, 1913. Serial No. 773,711.

To all whom it may concern 'Be it known that I, HARRY E. AINE, a citi'- zen of the United States, residing at Richmond, in the county of Contra Costa and State of California, have invented certain new and useful Improvements in Machines for lrVinding Pipes or Pipe-Coverings, of which the following is a specification.

The present invention relates to improvements in pipe winding machinery and more particularly to that type of machine adapted for constructing wooden, wire wound, endless stave pipein the ditch or place where used, Iand the invention has for its principal objects to construct a machine which is capable of tightly winding a continuous spiral coil of wire about a pipe as the same is constructed, one which is so constructed as to be mounted on a formed pipe for rewinding the same should. the binding wire break; and one which is also capable of beingv adjusted over an assembled pipe when it is desired to cover the same with an endless wire wound wooden stave covering or protector without interrupting the assembled structure.

The invention consists primarily in' constructing all parts which surround the pipe in sections, that the same may be employed for winding a stave pipe as the saine is assembled, oi may be mounted on a constructed or laid pi )e without cutting the same, should it be desired to rewind the same or provide the same with an additional covering or protector.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the ac-` companying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion,.size and minor details of construction, within the scope of the claims, may be resorted to without de arting from the spirit or sacrificing any o? the advantages of the invention.

To more fully comprehend the invention, reference should be had to the accompany- @ing drawings in which is disclosed one form of my invention employed in winding a protecting covering about an assembled pipe, and in which- Figure I is a partly brokenA side elevation of my improved winding apparatus. Fig. 2 is a side view of the winding device with the pipe in section and disclosing the steadying;

means for the same. Fig. 3 is a sectional view taken on line 3-3-F ig. 2, disclosing the adjustable pitchgiving bars. Fig. 4 is a View .in detail of the winding wire tension device. Fig. 5 is a cross section of the toothed annulus taken on line 5-5 of Fig. 2, disclosing the supporting rollers operating in the grooves at the sides of the annulus.

Referring more particularly to the several figures of the drawing, wherein like reference numerals indicate corresponding parts throughout the several views-1 indicates a suitable pipe, preferably of metal, about which is positioned the wooden covering composed of the staves 2 which are positioned around the same with the abutting ends of engaging staves arranged in staggered relation to each other, and which are retained in position about the pipe by an endless spiral winding of wire.

For the purpose of winding the assembled covering, I employ the lsemi-cylindrical shells 3 and 4 adapted to encircle the staves or covering in slight spaced relation thereto, and said shells are provided on their adjacent meeting .edges with bolt flanges 5 through which extend the headed bolts 6, carrying at their ends the nuts 7, between which and one of the flanges are interposed the coiled springs 8, which serve to force the semi-cylindrical shells together about the covering. Surrounding the semi-cylindrical shells and secured thereto is a suitable annular gear formed of the two semi-cylindrical sections 9 and 10, the ends of which overlap and are secured together by suitable transversely ektending bolts 11, which are seated in the annular channels 12 formed in the opposite side walls of the sections. Suitable rollers 13, carried by inwardly projecting studsl 14: formed on the innerl faces of cheek.

plates 15, operate in the grooves or channels 12 and the upper ends of the cheek plates are connected to a laterally projecting arni 16,

which is connected at its end through a link 17 with a suitable spring arm or supporting member 18 carried by a truck 18', the structure being hereinafter termed a dolly, and

the same is movable on a suitable trackway 182 positioned at one side of the ditch in which the pipe or covering is being constructed, which permits of the advancing of the winding apparatus on the pipe as the wire is wound thereon. Power is transmitted to rotate the annulus by a suitable pinion 19 to which power may be transmitted fi'om any suitable source, such as a motor 2O or other power generating device.

From the above description it will be apparent that by constructing the shell of two semi-circular halves and clamping the same about the pipe that. no supporting structure isneeded and that the arm 16 and dolly will maintain the driving mechanism stationary relative to the annulus and the shell, and will at the same time permit the same tomove longitudinally of the covering to properly wrap the wire therearound.

Positioned between the inner surfaces of each of the semi-circular shells 3 and 4 and the staves 2, and secured midway of their length to the pivot pins 21 carried by the shells, are a plurality of equidistant pitch giving bars 22, preferably V-shaped in cross section and curved to conform to the inner surface of the semi-cylindrical shells. These pitch giving members project inwardly and substantially act as threads when embracing the exterior surface of the staves. The

corresponding ends of the pitch giving bars` carried by the respective shellsl are pivotally secured to plates 23 provided vwith studs 24 which operate in slots 25 formed in the shells, and the opposite adjacent ends of the bars are also pivotally connected to plates 26 carrying studs 27 which are slidably mounted in grooves 28 formed in the shells, and said studs 27 carry on their outer ends angle plates 29 through which extend the bolts 30, which are adjustably retained in position relative to other angle plates 31 securedvto the exterior of the shells by the nuts 32. It'will be apparent that by adjusting thenuts 32the same will operate the plate 26 associated therewith, and the inclination of the pitch giving bars associated with one of the sem-circular shells` will be varied simultaneously, and that the adjusting of said pitch giving bars may be accomplished while the structure is in operation and without removing it from the structure which is being wound.

The wire as wound onto the staves passes through a tension device mounted on the exterior surface of one lof the shells and the same consists of a pair of longitudinally spaced plates 33, flanged 'at their lower ends, and secured to the shell by the bolts 34, and rotatably supported between the plates are the spaced, grooved supporting rollers 35 preferably three in number, betweenwhich are positioned the tension rolls 36 carried by journalsl 37, which operate in blocks 38, slidably mounted in slots 39 formed in the plates 33. through flanges 41 at the upper edges of the plates 33 provide the adjusting means for the tension rolls. y

The operation of the apparatus is as follows :-The staves are positioned about the pipe it is desired to protect and temporarily Adjusting screws 40 threaded retained in position in any suitable manner, and the semi-circular shells 3 and 4, each carrying the V-shaped pitch giving bars 22, are placed around the staves being retained in position by the bolts 6. The sectional annulus 9 i is detachably secured over the shells 2 and 3, the partsof the annulus be- -ing secured together by the bolts 11, and

the annulus and shells are rotated to advance spirally and progressively along the staves by power transmitted through the pinion 19. Wire 44 from a reel 45 is lead around below the covering between the reel and the ends of the semi-circular shells 3 and 4, and upwardly, as at 46, through the tension device and passing between the rollers 35 and 36, thence through a perforation 46 in the shell 3 and ontothe exterior gressively longitudinally of the covering or protector. It is apparent that by the annulus rotating in the direction as in Fig. 1,

the wire 44 will be tightly wound around the protector or covering and by reason of the spiral advance of the shells about the covering or protector, the dolly will be' automatically advanced along the track and will prevent the movement of the motor 20- and pinion 19 in the Vdirection of rotation of the annulus. A

While I have shown'a structure wherein the semi-circular shells are detachably secured to the annulus and are tightly encircled by the same, it will be apparent that` the same annulus may be employed with other shells of less diameter than those shown by simply positioning spacing blocks between the annulus and the shell.

It will also be apparent that the machine as at present constructed is capable of being positioned over a laid or constructed pipe without cutting the same should it 'be desired. to rovide a wooden stave covering for the p1pe, or the machine is equally adapted for constructing endle stave, wire woundpipe in the ditch or place where'used.
